Liquid armour 'can stop bullets'
A liquid armour has been shown to stop bullets in tests carried out by UK scientists at BAE systems in Bristol.
The researchers have combined this "shear-thickening" liquid with Kevlar to create a new bullet-proof material.
The company is keeping the chemical formula of the liquid a secret, but it works by absorbing the force of the bullet strike and responding to it by becoming much thicker and more sticky.
The BAE scientists describe it as "bullet-proof custard".
